<p>Reports combination of <code>null</code> and emptiness checks that can be simplified into a single check.</p>
<p>The quick-fix replaces highlighted checks with a combined check call, such as <code>isNullOrEmpty()</code>.</p>
<p><b>Example:</b></p>
<pre><code>
  fun test(list: List&lt;Int>?) {
      if (list == null || list.isEmpty()) {
          println("List is empty!")
      } else {
          println(list.joinToString())
      }
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  fun test(list: List&lt;Int>?) {
      if (list.isNullOrEmpty()) {
          println("List is empty!")
      } else {
          println(list.joinToString())
      }
  }
</code></pre>
